The present invention relates'to a closure albracket 11 depending from the cross memfor the upper end of an oil well tube when kber 9 and having journaled therein apulleyl y said tube is being pulled from the well for '12. My improved 4cap is denoted generally the purpose of preventing Vthe oil from pourby the letter C and comprises a disk 14: Vhaving out of the tube and soakingthe roust-` ing an annular depending flange 15 the en' about. f lower end of which is provided with an It is the common practice to pull the tubes inwardly directed bead 16 formed wlth a fromthe oil well without ltaking any prenotch 17. A gasket 18 is mounted in the cautions to prevent the soaking with oil of cap, being held in placeby the flange 15.
